In 2280, he became infatuated with a visiting Terellian girl named Jara. Tuvok again journeyed across the desert and studied for several months under the tutelage of a Vulcan master in another attempt to purge his emotions. (VOYepisode: "Gravity")

In 2289, Tuvok was preparing for a life of study, logic, and the Kolinahr discipline, when his parents, believing that his galaxy-view was too narrow, enrolled him in Starfleet Academy. Reluctant to disobey his parents' wishes, Tuvok pursued a Starfleet career. (VOYepisode & novelization: Flashback)

During his time at the Academy, Tuvok was left constantly puzzled by human behaviour and found himself the victim of several practical jokes laid by his roommate CadetScott Hutchinson. He found himself fascinated by a fellow cadet named Sophie Timmons who had developed an interest in the Vulcan way of life and did not show her emotions. After spending some time together, Sophie broke down and admitted she had developed romantic feelings toward Tuvok, but of course, Tuvok did not reciprocate. He chose to end their friendship, and was left more disdainful of humans than ever.

As a freshman at the Academy, Tuvok beat an athlete from UCLA in the four hundred meter hurdles competition. (VOYnovel: Pathways)

In the 2340s, Tuvok fulfilled a life-long ambition by making a pilgrimage to Mt. Seleya on foot across Vulcan's Forge. The journey took him several months. During the journey, Tuvok came to the conclusion that it was time for him to give something back to the universe that had given him so much and that the best way to do that was to re-join Starfleet. (VOYnovel: Pathways)

Soon after Tuvok's return to the Wyoming, Captain Broadnax suddenly and unexpectedly died, and command of the Wyoming was given to Akaar.

In October of 2349, Tuvok and Akaar were marooned on a barren, barely habitable rock known as Planetoid 437 for nearly two weeks. Akaar felt the honorable thing to do was to perform the w'lash'nogot, a Capellan suicide ritual, so that the dwindling supplies would be enough for Tuvok to survive. Tuvok refused to let his old friend and Captain die, and saved Akaar's life.

Despite the Wyoming rescuing the pair two days later, Akaar saw the disruption of the ancient ceremony as a betrayal by his old friend, and quickly arranged for Tuvok's transfer. (TTNnovel: The Red King)

Shortly after the undercover mission to Romulan space, Tuvok was assigned to Starfleet Command reviewing the tactical and procedural records of starship captains. One such record was for AdmiralOwen Paris's protégée, Captain Kathryn Janeway of the USS Bonestell. Tuvok was appalled at Janeway's lack of attention to tactical and security matters in deference to scientific research. AdmiralMcGeorge Finnegan felt that Tuvok would be well-suited serving under Janeway on her next assignment, the USS Billings, where Tuvok could advise Janeway on tactical and security matters.

While on Voyager's shakedown cruise near the Badlands a few weeks later, Tuvok's sensors detected the energy signature of one of the Malkus Artifacts, and believed it to be in the hands of the Maquis. Tuvok and the ship's first officer, Aaron Cavit, devised a plan in which Tuvok would infiltrate the Maquis and gather intelligence after Voyager was on active duty. The discovery of the Malkus Artifact required that the plan be accelerated.

With the help of the USS Hood and Captain Robert DeSoto, Tuvok infiltrated the Maquis cell run by former Starfleet officer Cal Hudson. Soon after, Hudson's vessel rendezvoused with the Geronimo, commanded by another former Starfleet officer named Chakotay, which had been catastrophically damaged by an Andorian named Tharia ch'Ren, who had found the Malkus Artifact. The Maquis cell followed Tharia to the planet Slaybis IV, where Tuvok was among those that confronted Tharia, and witnessed his death. Tuvok acted to make certain Starfleet obtained possession of the artifact, and continued his undercover assignment, joining Chakotay's cell. (VOY - The Brave and the Bold, Book Twonovella: The Third Artifact)

Captain Janeway soon came looking for her tactical officer, and Voyager was soon caught up in the same Nacene displacement wave and brought to the Delta Quadrant, 70,000 light-years from home. As both Janeway and Chakotay's crews were stranded and missing personnel, the two captains decided to pool their resources. (VOYepisode: "Caretaker")

Tuvok, reinstated as Voyager's chief of security, was initially distrustful of Chakotay and the Maquis crew, and even revoked Chakotay's command codes early in Voyager's journey when Captain Janeway was rendered comatose. (VOYshort story: "Command Code")

Convinced that the dangers of the vastly unexplored Delta Quadrant required a special tactical approach, Tuvok created a team of elite tactical officers in 2376. Known as the Hazard Team, these officers would respond to the ship's most dangerous situations, be they away missions or hazards onboard the ship. Hazard Team immediately proved useful, helping to drive Scavenging pirates and the Borg off the ship, as well as helping Voyager escape a dampening field which held the ship in a desolate wasteland known as the Forge. Captain Janeway told Tuvok that upon the return of the ship to the Alpha Quadrant, she would recommend that Hazard Teams be deployed throughout Starfleet. (VOYcomic: "Elite Force (comic)", VOYvideo game: Elite Force)

In 2377, Tuvok was diagnosed with a degenerative neurological disease that would eventually eat away at his self-control. The cure was a relatively simple one, but required a mind meld from a compatible Vulcan, usually a blood relative. Fortunately for Tuvok, Captain Janeway managed to ride Voyager through a Borgtranswarp hub all of the way back to the Alpha Quadrant, where Tuvok was soon cured after a brief mind-meld with his son, Sek. (VOYnovelization: Endgame; VOYnovel: Homecoming) The ship's escape was largely due to the heroism of the Hazard Team, proving that Tuvok's idea can truly make a difference aboard a starship. (TNGvideo game: Elite Force II)

Upon his return to the Alpha Quadrant and reunion with T'Pel, Tuvok accepted a position as an instructor at Starfleet Academy and a promotion to Commander. He was briefly reunited with his Voyager shipmates when a Borg virus infected Earth, and the Voyager crew was suspected of carrying it to the Federation. (VOYnovel: The Farther Shore)

Tuvok was onboard the Titan when she was transported to the satellite galaxy, the Small Magellanic Cloud, home of the human offshoot known as the Neyel, whom Tuvok had encountered while serving on the Excelsior. Also onboard the Titan was Tuvok's old friend from the Excelsior and the Wyoming, Leonard James Akaar, now an Admiral.

After the evacuation of as many of the Neyel people as the Titan could carry from the growth of the proto-galaxy known to the Titan crew as the Red King, Akaar apologized to Tuvok for the way he treated him all of those years ago and for the years of friendship lost.

Captain Riker was impressed with Tuvok's performance during the crisis, and offered him a permanent position onboard the Titan as tactical officer. Not willing to be separated from his wife for another extended period, Tuvok only agreed after Riker approved of T'Pel's moving onto the ship with her husband. (TTNnovel: The Red King)

In early 2380, he was briefly attached to the USS Enterprise-E in order to help integrate the Hazard Team into the ships operations, and was subsequently involved in the ship's battle against the Exomorphs. He also served as the ship's Chief of Security and Tactical officer while Worf was on leave, and assisted in the heroic defense of the ship from Idryll invaders. (STvideo game: Elite Force II)

In early-2380, shortly after Titan began her mission of exploration of the Gum Nebula, Tuvok came under the control of the cosmozoan species known as the Star-jellies. While under the Star-jellies influence, Tuvok assaulted shipmate Melora Pazlar and transmitted classified data to the Star-jellies. No charges were brought up against Tuvok as it was determined that he was not acting of his own accord. After the incident, Lieutenant Pazlar asked Tuvok to instruct her in various means of self-defense. (TTNnovel: Orion's Hounds)

After the unfortunate incident between Tuvok and Pazlar, he worked with her to develop a suitable self-defense routine, mostly utilizing methods of avoidance and escape rather than return force. Tuvok continued to serve as the Titan's CTO and second officer into 2381 when the Borg began their invasion of Federation and surrounding space. Although the Titan was too far away to be of assistance, Tuvok analyzed the dispatches from Starfleet Command, attempting to identify any potential aid he could render. When the ship discovered a hidden planetary system, Tuvok was part of the away team that took a shuttlecraft down to the surface, where he later recognized and identified CaptainErika Hernandez, missing commanding officer of the NXColumbia, who had been living with the Caeliar on Erigol and now New Erigol. (ST - Destinynovel: Gods of Night)

After Erika Hernandez issued the declaration that the away team were permanent residents of New Erigol, Turvok scouted the city of Axion with first officer Christine Vale. They observed Caeliar movements until security officers Dennisar and Sortollo joined them, revealing the constant surveillance by their captors. Tuvok expressed the opinion that they could not trust Erika Hernandez, considering her compromised. Tuvok later initiated separate mind-melds with Christine Vale and Ranul Keru to formulate an escape plan; Tuvok found her mind to be driven by intense personal conflicts, but his was extremely disciplined. Tuvok provided the diversion by creating a harmonic pulse to shatter a crystal tower which allowed Keru to beam aboard the shuttlecraft Mance, but the Caeliar Inyx stopped Keru from lifting off the surface. Following the failure, at the full away team debriefing, Tuvok telepathically picked up on Deanna Troi's distress and questioned Vale about it, but was told to remain silent on the issue. (ST - Destinynovel: Mere Mortals)

When Captain Riker was forced to abandon the away team, the situation seemed hopeless; however, the Caeliar eventually decided to release their prisoners, allowing them to return to Titan for the final confrontation with the Borg. Tuvok soon learned that one of his sons, Elieth, had been killed in the Borg attack on Deneva. In the wake of the Borg's dissolution at the hands of the Caeliar, he visited the ravaged planet with his wife, but struggled to cope with the emotional toll that the loss of his son had. (ST - Destinynovel: Lost Souls)

In 2382, Tuvok and a Titan away team boarded the ancient terraforming device known as Brahma-Shiva on a mission to download the artificial intelligence (believed to be the Great Egg Bringer S'Yahazah herself) of the device and then destroy the platform before the Gorn could use it. Following the disabling of a data module and SecondGen White-Blue by the consciousness, Tuvok decided to Mind meld with the lifeform in order to download its knowledge into his own consciousness and to disable the device before it could terraform the planet Hranrar. Tuvok's mission was successful; however, he remained unconscious for several days following his mission. When he awoke the terraforming knowledge of Brahma-Shiva had been downloaded into his memory; but he was uncertain if that was a gift or a curse. (ST - Typhon Pactnovel: Seize the Fire)

Tuvok temporarily assumes command.

At an unspecified date, Tuvok worked with assistant Chief engineerWesley Crusher to decipher a data stream. During their efforts, Titan was attacked by a Klingon ship, and Tuvok took command to defend the ship. He decided not to retreat, but rather to allow the Klingons to defeat themselves, by utilizing the data stream. (TTNmovie: Star Trek: The Tour)

The USS Voyager remains in service under the command of now Rear Admiral Tuvok in 2409. He commands the vessel as part of a task force composed of Federation, Klingon Empire, and Romulan Republic vessels that enters Fluidic Space to halt an invasion by the Borg Collective. Tuvok later was part of a team sent to a facility close to the central star of the Solanae Dyson Sphere to neutralize it's ability to travel across space. During the operation, an Iconian Gateway is opened, and Tuvok and the other surviving team members pursue a VothCitadel class vessel through it only to find themselves in the Jenolan Dyson Sphere. After repelling an attack on the sphere by Species 8472 (also known as the Undine), Tuvok manages to prevent a second altercation when members of the Romulan/Federation/Klingon alliance begin arguing over ownership of the Jenolan sphere. A year later in 2410, Tuvok hosts a summit at the Jenolan sphere to discuss ownership of the sphere as well as to address the threat of Species 8472. The talks are interrupted when the Undine use the Iconian gateway in the sphere to launch a massive attack on earth Spacedock. After repelling the attack, Tuvok is subjected to a psychic attack by an Undine posing as Eric Cooper. Tuvok then takes advantage of the attack to discover the Undine's true target; the Klingon homeworld. Tuvok then takes Voyager to Qo'noS and assists in stopping the Undine from destroying the planet, leading to an end to hostilities between the Federation and the Empire. (STOmissions: "Fluid Dynamics", "A Step Between Stars", "Surface Tension")

When the decision was made to initiate Operation Delta Rising, Tuvok was able to recruit his old crewmates Harry Kim, Seven of Nine and the Doctor to aid him in their return trip to the Delta Quadrant. However, not everything was so easy; Eric Cooper was busy pounding away at Tuvok's mental defenses, forcing Tuvok to recruit the captain who had aided him earlier. Through this action, they were able to drive out Cooper from Tuvok's mind and locate him within Fluidic Space, using a powerful new bioship. The two were able to enter the ship and make its way to the bridge, where Tuvok was able to mind meld with the ship and convince it and the Undine that their continued assaults again the Alpha Quadrant powers would only make them weaker. When Cooper protested, the ship determined that it was Cooper who was weak and destroyed him. (STOmission: "Mindscape")

Soon after, Tuvok went to meet up with Neelix, who was set to take the Talaxians at the asteroid base to their new home on New Talax when Kazon raiders struck. The raiders were driven away and Tuvok and the starship captain went to meet Neelix and prepare the Talaxians for their trip. (STOmission: "Reunion")

While Voyager and a taskforce consisting of eight other ships were investigating recent suspicious activities being carried out by the Cardassians on the Federation border in 2373, the ships were fired upon by Galor-class warships armed with phased polaron beam weapons. Unbeknownst to the Federation at this time, these weapons had been provided by the Cardassians' newfound Gamma Quadrant allies, the Dominion. The Cardassians had made contact with the Dominion several years earlier via the wormhole which they discovered in the Bajoran sector, the existence of which they kept secret from the other major Alpha Quadrant powers.

In the midst of the battle, Voyager was able to gather detailed sensor readings. Moments before the ship was destroyed with all hands, Tuvok transmitted these sensor readings to Starfleet Command, enabling the Federation to develop countermeasures against the phased polaron beam weapons.
